When you go food shopping, what's the first thing you look at? The packaging. So when you see pictures of healthy berries, you think: "I'm getting healthy berries." Look, no one thinks you're getting a full day's serving of fruit in a box of cereal, but if the label shows berries, shouldn't you be getting some? Experts say some of the biggest food companies are fooling you. Those so-called berries? You won't believe what they're really made of.

Take a spin in the grocery store: It's like a berry bonanza. From your favorite breakfast foods to those popular energy drinks, even kids' yogurts, the labels grab you: Real fruit, full of vitamins. And many of us eat it up.

“It gives the impression that it's healthier," said one shopper. "Blueberries in cereal, that's great," another told us. "You get everything in one box."

But some experts say it's a trick — that food companies go a long way to fool you. Take Special K Fruit and Yogurt cereal: Look at all those fresh berries on the front of the box. Reaching into one, I told Michael Jacobson, who runs the Center for Science in the Public Interest, a consumer watchdog group, "This looks like a real berry to me."

So if consumers feel that way, why do the companies still do it? We wanted to ask the group representing the food industry, but they declined our request for an interview, instead sending us an email saying they "support laws requiring labels to be truthful and non-misleading," and these labels "are permitted" under FDA regulations.

"The Food and Drug Administration is asleep at the wheel," Jacobson told us. "It rarely brings complaints against these companies."

"Why?" we asked.

"I suspect the Food and Drug Administration doesn't want to tangle with big companies who could keep them tied up in court for years," he replied.

He said one of the trickiest is vitaminwater. Take their kiwi-strawberry flavor: "We're suing Coca-Cola, which owns vitaminwater, because there aren't any strawberries and there aren't any kiwis in there," Jacobson said.

"Companies are gonna make a lot more money if they can imply that there are berries in the product, but not put them there," Jacobson said. "They're saving a lot of money, but they're cheating consumers."

The food companies told us some of that real fruit on the package is meant as a serving suggestion, and is disclosed in small print. The FDA says it does inspect labels, and it's cracking down on companies that break the law. The agency told us it's your responsibility to read the entire label, not just the front.
